This isn't about do you like Mike Jones. This isn't even about the guest shooter.
I'll go with Mike on this one. It turned out to be a good story.
Spoiler. 22LR @ 710 yards? I'd go with not possible. However, he did land one within near spitting distance and that in itself is outstanding.
The guest shooter did get a hit on a coke can at 300 yards. Put that in perspective for the casual shooter, pretty much not going to happen.
For the experienced rimfire shooter it may happen. Give an experienced shooter quality ammunition and the chances increase. Give an experienced shooter a purpose built rifle, quality ammunition, optic, and easy environmental, then it's on the edge of consistency.
At 300 yards.
Move the goalpost out to 400 and cut the hit probability in half.
Move the goalpost out to 500 and cut the hit probability in half again.
Move the goalpost out to 600 and cut the hit probability in half again.
Move the goalpost out to 700 and ...
I know there are some rimfire shooters here that have thousands of dollars in equipment and tens of thousands of rounds experience .
My own experience pales in comparison. Still, I have a very good idea of what it takes to get out to 300 yards with iron sights and 500 yards with optics. At 300 yards and iron (quality peep sights) I can worry a target. At 500 yards with a good optic) I'm somewhere between minute of garage and barn door.
So please, what does the experienced rimfire crowd have to say about this?
